Abstract
A clamp mechanism uses a fixed spring force input caliper with friction pads in frictional contact with a variable thickness portion of a disc, where the disc thickness, thus the clamp force, varies as the disc rotates through one rotation or less.
Claims2
A variable force clamping mechanism comprising:
- a. a clamp mechanism with fixed input force from a spring or the like,
- b. friction pads operated by said mechanism,
- c. a disc whose thickness about its circumference varies with respect to degree angle about said disc,
- d. said pads in frictional contact with the portion of said disc having variable thickness.
1 more element
Variation in thickness of said disc, relative to the position of said pads, causing a corresponding variation in the position of one or both of said pads, causing a proportional variation in the spring input force of said mechanism, producing a proportional change in friction force between said pads and said disc.
